' PIPE-COUPLING.

To all whom it may concern.- Be it known that I, HERMANN NAGEL- SCHMIDT, a citizen of the United States, residing at St. Louis,'State of- Missouri, have invented certain new and useful Improvements in Pipe-Couplings, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in pipe-couplings; and it consistsof'the novel features herein shown, described, and claimed.

The object of my invention is to construct a coupling provided with two fulcrums, one located on each member of the coupling and arranged to fit over and into the lug and held in position and both members tightly connected by the use of wedges.

A further object of my invention is to arrange both members of the coupling, each provided with a flange extending half-way the said flanges will communicate with each other, and when tightly connected by the fulcrums and wedges a perfect leak-proof joint is accomplished. Figure 1 is a top plan view of my improved coupling in connective position. Fig. 2 is a side view of the same. Fig. 3 is a sectional view taken on the line 3 3' of Fig. 2, viewing in the direction indicated by the arrow. Fig. 4 is a longitudinal sectional view through the coupling, showing the relative position of the flanges.

In the construction of my improved coupling I provide yok-es 5 and 6, the said yoke 5 being pivotally connected, by means of the screw 7, to the member Sand the yoke 6 being similarly connected to the member 9. The ends 10 and 11 of said yokesare' located between integral lugs 12 and 12 and 13 and 13, the purpose of said lugs being to stiffen the yokes when pressure is'brought upon the same. The ends 141 of said yokes are formed in a loop arranged to straddle the ends 15 of the loops 16. The said loops 16 are composed of two members and arranged a sufli- Specification of Letters Patent.

cient distance apart to straddle the elongated integral lugs 17, located on each member of the coupling. The ends 18 of the lugs 17 are provided with a groove 19, and both members of the loop 16 are provided with an elongated slot 20, into which is inserteda tapering wedge 21, the purpose of which is to draw upon the yokes and tightly connecting the meeting edge of the members when the wedges '21 are tightly driven into the elongated slots and communicating with the groove 19. 'The members 8 and 9 are provided with flanges 22 and 23, arranged half-way around the periphery, (see Figs. 1 and 2,) and the contacting edge is provided with a strip of packing material'24.

To connect my improved coupling, both members are placed together and the loops passed over the lugs 17, the wedges are inlocated on each side of the pivot; a flange formed on one-half of each of the contacting edges of said members; a loop pivotally connected to the outer ends of the yokes; a lug formed on each of said members to receive the loop; and a locking device, whereby said loops are held in locked position with said lugs; substantially as specified.

In testimony whereof I aflix my signature in presence of two witnesses.
